  • Throttle shaft seal for a throttle body
    Patent number: 5522361
    Abstract: A throttle body (10) for use in the air intake system of an internal combustion engine. The throttle body (10) includes a throttle body housing (12) having throttle shaft bearings (22) mounted within it for receiving a throttle shaft (34). The throttle shaft (34) is mounted within the bearings (22) and coupled to a throttle position sensor (26), which is mounted to the throttle body (10). The throttle shaft (34) includes mounting surfaces (40) aligned with the bearings (22) and a sealant (42) applied between the mounting surfaces (40) and the bearings (22) to both seal the intersection between the two and to substantially eliminate axial movement of the throttle shaft (34) relative to the throttle shaft bearings (22).
